Scale. Growth.
.
Between 1997 and 2017, global electricity output climbed an average 571 terawatt-hours per year. Merely keeping pace with growth in electric demand would require installing 14 times as much photovoltaic capacity as Germany’s entire installed base, and it would have to do so every year.

or wind.
.
Thus, just to keep pace with growth in electrical demand, the world would have to install twice as much wind-energy capacity as now exists in all of China, and it would have to do so annually.
.
And that is just growth of electricity consumption. Not to mention replacing all electricity. And then replacing all the remainder of primary energy consumption which is another 4 times electricity.
.
the world’s demand for oil will hit a record 100 million barrels per day. That would be an increase of about 1.8 million barrels per day over 2017 numbers.
.
global solar production totaled the equivalent of about 2 million barrels of oil. Just enough to match the growth in oil consumption if we weren't already comparing solar to the growth in electrical consumption. And oil is only 40% of primary energy.
